Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Diverse cell-specific patterns of alternative polyadenylation in Drosophila

Bart Deplancke, Sandy Lee

Most genes in higher eukaryotes express isoforms with distinct 3' untranslated regions (3' UTRs), generated by alternative polyadenylation (APA). Since 3' UTRs are predominant locations of post-transcriptional regulation, APA can render such programs condi ...

Krab-containing zinc finger protein and cancer

Didier Trono, Priscilla Turelli

The present invention provides methods for detecting cancer as well as agents and compositions for treating cancer by modulating the expression and/or activity of one or more i) KRAB-containing zinc finger protein (KZFP), ii) mRNA encoding a KZFP, and/or i ...

Circadian dynamics of RNA localisation in the mammalian liver

Clémence Yumie Syloun Hurni

Gene expression in eukaryotes is a complex multi-step process. It starts in the nucleus with transcription, the synthesis of a mRNA copy from a DNA template. While in the nucleus, the RNA transcript is subject to multiple co- and post-transcriptional modif ...

The phase separation-dependent FUS interactome reveals nuclear and cytoplasmic function of liquid-liquid phase separation

Helen Lindsay

Liquid-liquid phase separation (LLPS) of proteins and RNAs has emerged as the driving force underlying the formation of membrane-less organelles. Such biomolecular condensates have various biological functions and have been linked to disease. The protein F ...

Space-time logic of liver gene expression at sub-lobular scale

Felix Naef, Clémence Yumie Syloun Hurni, Colas Noé Droin

The mammalian liver is a central hub for systemic metabolic homeostasis. Liver tissue is spatially structured, with hepatocytes operating in repeating lobules, and sub-lobule zones performing distinct functions. The liver is also subject to extensive tempo ...

Organisation and dynamics of mitochondria and their RNA.

Timo Henry René Rey

The organisation of molecules into dynamic cells, and collaboration of many of those cells over a billion years led to the evolution of human life. During the last century, biologists then began to unravel the marvels of cellular organisation with ever in ...

Detecting DNA and RNA and Differentiating Single-Nucleotide Variations via Field-Effect Transistors

Nako Nakatsuka, Yang Yang, Bowen Zhu

We detect short oligonucleotides and distinguish between sequences that differ by a single base, using label-free, electronic field-effect transistors (FETs). Our sensing platform utilizes ultrathin-film indium oxide FETs chemically functionalized with sin ...

Robust landscapes of ribosome dwell times and aminoacyl-tRNAs in response to nutrient stress in liver

Felix Naef, Cédric Gobet, Frédéric Bruno Martin Gachon, Benjamin Dieter Weger, Nagammal Neelagandan

Translation depends on messenger RNA (mRNA)-specific initiation, elongation, and termination rates. While translation elongation is well studied in bacteria and yeast, less is known in higher eukaryotes. Here we combined ribosome and transfer RNA (tRNA) pr ...

Mitochondrial RNA granules are fluid condensates positioned by membrane dynamics

Suliana Manley

Phase separation concentrates mitochondrial RNA granules. Here Rey et al., show that mitochondrial RNA granules (MRGs) behaviour is consistent with liquid-liquid phase separation (LLPS) and their fusion coincides with mitochondrial remodelling. Mitochondri ...

The ETFL formulation allows multi-omics integration in thermodynamics-compliant metabolism and expression models

Vassily Hatzimanikatis, Pierre Guy Rémy Salvy

Systems biology has long been interested in models capturing both metabolism and expression in a cell. We propose here an implementation of the metabolism and expression model formalism (ME-models), which we call ETFL, for Expression and Thermodynamics Flu ...
